    摘要: Combination of a message board and computer equipment for conveniently writing and/or maintaining notes while working on or near a computer. The message board can be written and rewritten upon, used to post paper notes or photographs, or both. The message board is attached to the perimeter or side of the computer monitor or case, or used in conjunction with the keyboard or mouse. The message board can be made of traditional materials, or erasable and malleable metals or plastics, such as acrylic.

    摘要: The present invention relates generally to embedding and/or encoding auxiliary information within original data. For example, in one embodiment, a method of embedding auxiliary information in data is provided. The auxiliary information is not lost with compression of the embedded data. The embedded data initially includes a non-compressed form including the auxiliary information embedded therein. The method includes: (a) retrieving the auxiliary information from the non-compressed form of the embedded data; (b) compressing the non-compressed form of the embedded data; and (c) embedding the retrieved auxiliary information in the compressed embedded data, whereby the compressed embedded data comprises the auxiliary information embedded therein. Other embodiments are provided and claimed as well.

    摘要: Since the prior-art is based upon analog circuitry, it uses sinusoidal frequency and/or amplitude modulation to simulate a rotating speaker at a reasonable cost. This invention uses a process based upon theoretically derived frequency modulation (FM) and experimentally measured amplitude modulation (AM) to simulate the rotating speaker. The main FM equation is based upon the Doppler effect and is equal to one over one plus a sinusoidal velocity coefficient. The main AM equation has a much narrower peak than sinusoidal modulation. This invention also contains several novel methods to control the angular velocity of the speakers, including changing the horn's speed dependent upon the original audio, modeling the speaker's acceleration to allow the physically realistic transitions between angular velocities, and adding noise to simulate natural variations in rotation. The digital apparatus that implements this invented process includes a digital processor and memory. In summary, the invented process is much more realistic sounding than prior-art.

    摘要: This invention describes a method and apparatus for the increasing the robustness of embedded data. Since many times embedded data is susceptible to removal by an unauthorized person, one preferred embodiment enables an action such that removal of the embedded data provides the attacker no gain. In another preferred embodiment, recording devices are required to embed a registration code in copies, thus aiding in tracing illegal copies. Finally, dynamic locking, including modifying and encrypting the auxiliary data and applicable to all data embedding techniques, is shown to provide this robustness to duplication and modification. The apparatus implements the above two processes with a logic processor and storage unit.
